Any chance of more sql azure shows? If not, can you answer how sql azure works with SELECT and the two replication servers, are they used for load-balancing read requests like SELECT at all?

The reason for my asking is that this will greatly impact whether I must shard my DB or not since it's mostly SELECT-heavy and often with historical data not ever going to change, like how many orders where there last month by this or that customer or product blah-blah...
